Abstract
Embodiments of the present specification provide methods and apparatuses for generating two-dimensional codes. One method comprising: receiving, by a secure element chip comprised in a two-dimensional code display device, code information comprising an account identifier of an account associated with the two-dimensional code display device; in response to obtaining a digital certificate for a private key stored in the secure element chip, signing, by the security element chip, the code information by using the private key to generate signed code information; and providing, the signed code information to the two-dimensional code display device for the two-dimensional code display device to generate and display a two-dimensional code based on the code information, wherein the two-dimensional code comprises information associated with the account identifier and changes dynamically over time.
